#65 Remove declarations of split structs after --dosimplify

[Mark A. Hillebrand]

With --dosimplify (and without --no-split-structs), the original structure are still declared, although they are not used anymore.

Example: in the attached file, the local structure definitions of d and e are still present after --dosimplify.

rmtmps.ml should be able to delete unused structures, if you need this. We can't simply delete all struct definitions, because some structs can't be simplified (globals, return values, etc)
